Joules to Megajoules Conversion
Enter the energy in joules below to get the value converted to megajoules.
How to Convert Joules to Megajoules
To convert a joule measurement to a megajoule measurement, divide the energy by the conversion ratio. One megajoule is equal to 1,000,000 joules, so use this simple formula to convert:
The energy in megajoules is equal to the joules divided by 1,000,000.
Joules and megajoules are both units used to measure energy. Keep reading to learn more about each unit of measure.
Joules
The joule is the energy equal to the force on an object of one newton at a distance of one meter.[1] One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.
One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.
The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as J; for example, 1 joule can be written as 1 J.
Megajoules
One megajoule is equal to 1,000,000 joules, which are the energy equal to the force on an object of one newton at a distance of one meter.
The megajoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "mega" is the prefix for 106. Megajoules can be abbreviated as MJ; for example, 1 megajoule can be written as 1 MJ.
